CYME software will be your biggest assistant in your engineering works for your facilities and equipment.


Determining the current carrying capacity, which is the maximum current that the cables can withstand without deteriorating any of their electrical properties, is very important for the design of electrical installations. CYMCAP software allows users to design power cables and calculate their electrical parameters, as well as calculate the current carrying capacity and thermal effects of cables for installation conditions.

CYMCAP performs current carrying and thermal analyzes according to analytical techniques described by Neher-McGrath and International Standards IEC 287 © and IEC 853 ©. Detailed reports can be created with steady state and transient analysis capabilities.

Multiple Duct Banks and Backfills

This module provides the opportunity to define environments with multiple duct banks and filling materials with different thermal resistance.
The module calculates T4 values (thermal resistance of the environments) using the finite element method and then allows current carrying capacity analysis for cable installation.

Cables in Troughs

In this module, a long shallow rectangular channel is defined through which the walls, base and cover are made of concrete. Cables can be mounted on racks, on trays or on the ground.
The current carrying capacity and thermal analysis of the cables installed in the defined structures can be performed with this module.

Cables in Tunnels

The Cable in Tunnel, module allows the user to determine the steady state temperature and current carrying capacity, cyclic loading, emergency loading and temperature, and transient analysis results for cables installed in tunnels.

Multiple Casings

The Multiple Casing module for cables in one or more non-magnetic casing allows the user to carry out unbalanced load current carrying and thermal analysis at steady state.
Casing pipes can be buried in water, seabed, environments with different thermal structure or underground.

Circuits Crossing

This module allows the user to determine the steady-state current carrying capacity of two crossing cable systems.
When two circuits crossing, each acts as a heat source for the other. The amount of heat produced, the vertical distance between the circuits and the angle of transition affect the heat transfer.

Short-Circuit Cable Rating

The Short-Circuit Cable Rating module calculates the final temperature that the cable will reach during the short circuit. Another calculation that can be made with this module is the calculation of the maximum short circuit current that the cable can withstand.
The method is implemented according to the IEC 60949 © Standard. Thermal damage curve of the cable can be obtained with this module.

Magnetic Fields

After simulation of a steady state current carrying capacity or temperature, the module calculates the magnetic flux density that an underground cable installation will create at any point towards the ground.
In the analysis output to be made with this module, the magnetic flux density depending on the position can be obtained as a graph and table.

Duct Bank Optimizer

The Duct Bank Optimizer module allows the user to determine the optimum placement by performing thermal and current carrying analysis for different layouts of cables in a duct bank .
More specifically, the module can suggest various circuit configurations within a duct bank.

Cable Impedance Calculation

This module calculates the cable electrical parameters required to perform load flow and short circuit studies at power frequency (50/60 Hz).
As a result of the analysis, the impedance and admittance matrices of the cable together the symmetrical component values are also calculated.
